What is Thread insert
Thread inserts are basically used to create a metal thread, typically made out of brass or stainless steel in the assembly of many consumer products and electronics. It is also known as threaded bushing. It provides a durable threaded hole in a soft material and works as a mould, eliminating a machine operation or simplifying a changeover.
Thread inserts provide permanent, high-quality, wear-resistant internal threads mainly designed to get installed in drilled holes or molded forms in a simple and quick way. In-fact there are many advantages of using thread inserts.

Benefits of Thread Insert
Thread inserts can both enhance quality and improves performance. Thread inserts provide a high performance permanent thread that outdo and excel the strength of most parent materials.
Strength:
Wire thread inserts create internal threads as a result of their flexibility that which have a much improved distribution of residual stress loading. It enhances the load bearing capacity.
Corrosion Resistance:
Our insert thread is basically manufactured in nickel stainless steel and has excellent corrosion resistance that prevents adverse seizing and galling even at very high temperatures. Additional surface coatings are added for enhancing the resistance strength such as Cadmium, Silver or Molybdenum Disulphide, Zinc and Aluminum.
Cost and Weight Benefits:
They are less expensive and lighter than any other equivalent fastener. The compact size can be easily incorporated into any existing design. It enables the use of thinner sections or lighter parent materials without sacrificing thread strength.
Wear Resistance:
The brilliant surface finish and material hardness combine together create such internal threads that virtually eliminate friction induced thread erosion. Thread insert are perfect for applications that require repeated disassembly and assembly. All of the assembly torque is converted into clamping load virtually. Similarly thread friction is eliminated virtually and threads stay tight.
How to use Insert Thread:
Thread inserts are commonly the most strongest and least time-consuming fasteners utilized in any manufacturing set-up. You simply require a couple of relatively basic tools and a thread insert kit for installation. Also repairing damaged and stripped threads is an easy task that every mechanic and DIY enthusiast are mostly familiar with. Thread inserts extends the life structures and machinery. A little vibration and pressure is required to install the thread insert into a molded hollow boss and this process is called ultrasonic insertion. Heat insertion or thermal insertion employs heat to make thermoplastic material malleable in the particular area that needs insertion.
Types of Thread Inserts:
Depending on the application, Thread insert comes in various types and varieties.
Captive Nut: It comes into two basic styles, cage nut or clip-on nut. It is generally used to attach screws to sheet metal-parts too thin to be threaded. They can be attached, removed and reused with simple hand tools.
Externally Threaded Inserts: They have threads in the inside and outside of the insert. The insert is threaded into a pre-tapped hole or few inserts tap their own threads in a drilled or molded hole. Those inserts that are lock-via-friction or self-tapped are most commonly known by the trademarked names Tap-lock or Speedserts.
Helical Inserts: It is an insert made of coiled wire. These inserts are used to offer stronger threads in soft materials such as zinc die castings, magnesium, wood, aluminum etc. and provides a convenient means of repairing stripped-out threads.
Mold-in Inserts: They are internally threaded and have specially shaped outer diameter to anchor the insert in plastic. They can be heated and pressed into premade thermoplastics.
Press-fit Inserts: These are internally threaded and have knurled outer diameter. These are pressed into plain hole with an arbor press.
Potted Inserts: It refers to the application of epoxy to fix it to a panel like a sandwich panel or honeycomb which are often used in commercial aircraft.

Reasons to use Thread Insert:
Thread inserts are typically used for soft materials, however driving a screw or bolt directly into an object can cause lot of damage. Thread insert is placed inside the object after which threaded fastener is driven into the insert, making it easy for a screw or bolt to be driven all the way into it.
Applications of Thread Insert:
Thread inserts come in diverse range of sizes and diameter and are utilized in innumerable industries including electrical engineering, plant engineering, aerospace industry, defence industry, medical industry, telecommunications, automotive industry, transit products, and at many other places.
